The topic of this master thesis is the development of a new Web based HMI portal for Tetra Aptiva Aseptic. The aim is an open source code project where the basic idea is examined and partly implemented during this master thesis. Through a new technique, developed by Tetra Pak, clients can subscribe on topics of interest, which can be viewed on any trusted and connected computer within the Tetra Pa
A method for optimizing motion path definitions for servo unit motors of Tetra Pak’s packaging machines using optimal control is chosen, described and tested. Tetra Pak’s packaging machines are characterized by the use of servo motors to control repetitive actions that are repeated in cycles. When developing new packaging machines the motion path of the servo motor is always optimized in some way,
Ambitiösa ideal om tvärvetenskap är välkänt svåra att omsätta i praktiken, delvis beroende på att de motarbetas av hur många universitet är strukturerade. Detta är ett problem för doktorander i tvärvetenskapliga projekt såväl som för deras handledare. Tvärvetenskapliga doktorander har precis som alla doktorander ett forskningsämne i vilket de förväntas utvecklas till självständiga forskare men ockAmbitious ideals about interdisciplinarity are notoriously difficult to put into practice, partly because they are counteracted by how many universities are organised. This is a problem for doctoral students in interdisciplinary projects as well as for their supervisors. Interdisciplinary doctoral students, like all doctoral students, have a research subject in which they are expected to develop i
There is a growing interest in industry and academia in machine learning (ML) testing. We believe that industry and academia need to learn together to produce rigorous and relevant knowledge. In this study, we initiate a collaboration between stakeholders from one case company, one research institute, and one university. To establish a common view of the problem domain, we applied an interactive r
We introduce a family of stochastic optimization methods based on the Runge–Kutta–Chebyshev (RKC) schemes. The RKC methods are explicit methods originally designed for solving stiff ordinary differential equations by ensuring that their stability regions are of maximal size. In the optimization context, this allows for larger step sizes (learning rates) and better robustness compared to e.g. the p
Torrential rainfall predisposes hills to catastrophic landslides resulting in serious damage to life and property. Landslide inventory maps are therefore essential for rapid response and developing disaster mitigation strategies. Manual mapping techniques are laborious and time-consuming, and thus not ideal in rapid response situations. Automated landslide mapping from optical satellite imagery us
Firekite is a synchronous stream cipher using a pseudo-random number generator (PRNG) whose security is conjectured to rely on the hardness of the Learning Parity with Noise (LPN) problem. It is one of a few LPN-based symmetric encryption schemes, and it can be very efficiently implemented on a low-end SoC FPGA. The designers, Bogos, Korolija, Locher and Vaudenay, demonstrated appealing properties
IntroductionNine in ten of the world’s 1.74 million adolescents living with human immunodeficiency virus (ALHIV) live in Sub-Saharan Africa. Suboptimal adherence to antiretroviral therapy (ART) and poor viral suppression are important problems among adolescents. To guide intervention efforts in this regard, this review presented pooled estimates on the prevalence of adherence and how it is affecte
Water damage in the indoor environment is a rising issue within Nordic countries with about 90 000 cases in appx. 6.5 millioninsurance is reported annually in Sweden, and corresponding numbers are in Denmark and Norway. The question thenbecomes what type of measures residents, building managers, and insurance companies can take in the maintenance andoperation phase to decrease the impact of the wa
In the early decades of the 17th century, when the idea of the Swedish colony of New Sweden was conceived and realized, America had a vague place in popular consciousness. Knowledge of the new continent was rather limited, and early Swedish images of it were influenced by tales told by foreign travellers and sailors, by pictorial representations in prints and maps, and by news and reports publishe
In this study, we investigate for the first time the efficiency of an environmentally sustainable extraction technique (pressurized liquid extraction, PIE) in conjunction with a fast separation technique (ultra-high performance liquid chromatography, UHPLC) coupled to a selective mass spectrometry (MS) detector (quadrupole time-of-flight, qTOF) to extract, separate and quantify fifteen intact-gluc
Because new modes of action for the treatment of psoriatic arthritis (PsA) are emerging, it is important to understand the use of switching to a second or third antitumor necrosis factor (anti-TNF) agent. This study investigated drug survival and treatment response rates of patients with PsA undergoing second- and third-line anti-TNF therapy.
Objective: We have previously shown the capacity of tenascin-C (TN-C) to induce inflammatory mediators and matrix degradation in vitro in human articular cartilage. The objective of the present study was to follow TN-C release into knee synovial fluid after acute joint injury or in joint disease, and to correlate TN-C levels with markers of cartilage matrix degradation and inflammation. Method: Hu
Global public-private partnerships for sustainable development have been framed as new instruments that can increase the democratic credentials and effectiveness of global governance. This article revisits 10 years of scholarship and practice of the 348 Johannesburg partnerships, adopted at the 2002 World Summit on Sustainable Development and reaffirmed at the UN Rio+20 summit in 2012. The article
Based on a conceptualization of heteroactivism as a transnational phenomenon manifesting in local contexts to spread and express resistance to gender and sexual rights, this article aims to illuminate new dimensions of heteroactivism beyond a sole focus on gender and sexuality by bringing its specificities in the Swedish context to the fore. Drawing on digital ethnography with members of the neo-c
Strings is a participative performance that explores the driving forces of change and what personal motivations humans have for pursuing their vision. The site of the performance is the University of Lund with its atmospheric environment, history and diverse hubs of knowledgemaking in Lund and Malmö. The hosts are an international group of researchers from all faculties of Lund University covering
This chapter departs from two research projects to present the learnings, methodological challenges, and recommendations when involving users in participatory approaches of design research in home care. In the first project, older participants collected data through solicited diaries and photo elicitation, reflecting about their use of multiple medications and difficulties experienced with medicat
Barriers to healthcare for men who have sex with men (MSM) in sub-Saharan Africa (SSA) are rooted in stigma and discrimination against MSM fuelled by the criminalization of homosexuality. These barriers are influenced by factors involving MSM and the healthcare workers (HCWs). MSM are uncomfortable disclosing their identities and conceal symptoms of sexually transmitted infections (STIs), especial
The COVID-19 pandemic placed health sectors across the world under great pressure in terms of acute care and infection control. Policies responding to the latter led to a change in working practices among health practitioners, including nurses. The changes included establishing new patterns and protocols of risk work to mitigate infection risk in hospitals, but these new ways of working were somew
